IS there any physical difference between the La360 vs. magnum 5.9 Crankshaft???

The part number cross references the same on both RockAuto and AutoZone's websites when checked for a 91 D150 1/2 ton pickup with 360 and a 2000 Ram 1500 1/2 ton with a 5.9

I know the balancers and flexplates are different though from LA to magnum
